A source rock first approach to petroleum system analysis in the middle Magdalena Valley, Colombia
Abstract/Contents
- Abstract
- The Middle Magdalena Valley (MMV) is an intermontane basin and petroleum province in northern Colombia. A succession of organic-rich source rocks deposited in the Cretaceous show excellent petroleum potential and have generated economic oil and gas accumulations within the valley. However, understanding the chronology of source rock maturation and generation with respect to the other petroleum system elements is complicated by the impact of the Andean orogeny on northern South America. To help resolve the MMV petroleum system, biomarker chemometrics of oil samples from discoveries in the basin are used to identify distinct petroleum tribes with characteristics indicating the presence of multiple source rocks. An examination of pyrolysis data from MMV wells finds six Cretaceous intervals with favorable organic matter quality and quantity within the Tablazo, La Luna, and Umir formations. Finally, a 3-D model of source rock maturation and generation from the Cretaceous to the present-day enables the incorporation of all petroleum system elements within the context of the basin evolution. The timing of maturation-generation for the Cretaceous interval and the petroleum tribes identified both support that the upper members of the La Luna Formation and the Umir Formation generated the majority of hydrocarbons discovered in the MMV
